2003 expedition EB 5.4 problems (engine codes)so I have been getting an intermittent stumble occasionally on the highway. felt like a coil going bad. it is fine some days, bad on others.
fast forward to today---I am driving this morning and the stumble starts. then it starts feeling like it's running on 1 cylinder--I couldn't even get the thing up a hill. it threw 4 logged codes and 1 pending code:
logged codes: p0354 p0355 p0356 p0358
and the pending code is: p0320
I cleared the codes and let the truck sit for a few hours while I was doing other work, and tried driving around the block. it felt fine.
I don't know WTF is going on with it, but I can't see 4 coils going bad all at the same time. anyone seen something like this before? |

P0354 Ignition Coil D Primary/Secondary Circuit Malfunction P0355 Ignition Coil E Primary/Secondary Circuit Malfunction P0356 Ignition Coil F Primary/Secondary Circuit Malfunction P0358 Ignition Coil H Primary/Secondary Circuit Malfunction p0320 Crankshaft Position Sensor Circuit Failure
looks like you got some major electrical problems
Looks like the faulty Crankshaft Position Sensor Circuit Failure is the issue |

P0320 Ford Description
Ignition failure sensor is used to check whether the spark ignition is occurred correctly or not and also used to tachometer drive. The sensor monitors the voltage difference between a resistance which is on the battery circuit for ignition coil. When the ignition coil works properly, the electric current through the resistance is detected as voltage drop. This is confirmed for every ignition event with the crankshaft sensor and the camshaft sensor. If Engine Control Module (ECM) detects a malfunction, no ignition is possible, so the engine would not start. If there is no ignition signal for a predetermined cycle for one or two ignition coils, an ignition coil circuit failure exists.
I disagree The po320 is a byproduct of having four cylinders missing. While it seems unlikely i guarantee 100 percent if you replace the coil packs and spark plugs you will be good to go. Its very common on these tritons when one acts up others do to. Any relation to rain? On a side note you want to make sure you do it when the engine is cool. Your going to have to remove the fuel rail off the drivers side but thats no big deal. Use plenty of wd40 or similiar and have two 3/8 drive 3 inch extensions along with a 3\8 universal for the plugs. Do not do with the engine warm. There is only like three threads in the engine for the sparkplugs. When you pull them 4 missing cylinders your going to find condensation in the boots. if you cant do the total repair you can probably get away with removing the coil pack boots and blowing them out with a air hose as a temporary fix. I have saved a lot of money by buying the coil packs online. The chinese knockoffs wont last as long but are a lot cheaper. You can also buy the better ones on line. At dealer expect to pay about 80 to 90 a piece compared to about 100 to 120 for a whole set of 8 online. If it wasnt for the number 8 ide suggest blowing them out as a test. But the number 8 sucks to get to so i just suggest to replace them all. the number 5 is the one that requires the fuel rail come off so since 8 and 5 is there dont even screw with them. Just get a set online and you will be one happy camper. I have had some luck just using high pressure air and blowing out the coil packs without taking anything apart. Thats a very temporary thing tho. Like maybe a week if it doesnt rain at all. |

I did read about the coil packs causing RF interference that screws with the ECU. i'm no stranger to removing and replacing them---I've had to replace 3 over the years on my trucks due to ford's lovely spark plug thread design causing plugs to blow out and destroy them LOL. thank god for the timesert kit. I've also had around 10 bad coils on the work trucks. looks like i'm off to summitracing.com to pick up a set of accel coils. $185 for the set of 8, and they're not cheap Chinese knockoffs. I would rather have MSD, but they don't make them found them. $100 more, but they have them. |

The accels are good ones. Sounds like you are very well versed on them. 185 isnt that bad. Shouldnt say it but the last set i put in, i went to a upullit yard. Walked around and was able to find what looked to be about 8 brandnew ones on 3 seperate vehicles. Paid 4 dollars but clearly that wasnt for the 8 if you know what i mean. Was able to get all OEM like that. No way im paying 7 to 8 hundred dollars for a set from the dealer. Yea ford owners get very well versed on them and the insert kits. I only ever needed the kit once but when you need it you need it. |

I was shivering until around lunchtime. i'd go to the local junkyard for the coils, but the best one in the area was recently cleared out to build townhomes. someone must have overlooked the years of oil, gas, antifreeze, ETC that was seeping into the ground there. the other local one is in the flood zone and had over 6' of water in it two years ago. the coils are bad enough when they're not submerged for a week LOL. |

Yea i blew one out last year in the cold. It wasnt to cold for me. I went ahead and just drove it home and used the garage. Sucks to me, because of course it was the number 8 cylinder. Always seems to be the number 8 that the coil goes bad also. Has to be something about that as it always seems to me to start with the number 8. Like 5 trucks now and always seems like the number 8 is the prevailing culprit. Well accept the f350 that had the v10. That of course was the number ten. I try not to change the plugs unless i really have to. The last truck i managed to get 200,000 miles out of the plugs. I suspect that may have had something to do with some of the coil packs going out Because there was next to nothing left to them plugs. |

Try doing it with the Ford vans. I laughed one day when a driver brought one in and a plug shot through the fiberglass hood on the E-450. He was complaining about how it was missing and such. I asked if he noticed the hole in the hood. I received a blank look. |

just in case anyone was wondering.......... today 8 new plugs and 8 accel supercoils went in. she's running smooth as silk, has loads more power, and the gas mileage has shot up. oh----and no misfires the old coils were shitty to say the least---looks like water was pooling in at least 4 causing the plugs and springs to rust, forming a nice conductive path directly to ground. 5 of the 8 were also just hand tight. I'm hoping the truck runs right from now on. after seeing what came out, I think it should be GTG for a while.......... |

5 of 8 plugs were hand tight? Thats a new one. Glad the old triton is good. A buddy of mine just had a single one put in at the dealer. Cost 347.00 for one stinking coil pack installed. Just a little fyi to make you feel even better about it. I was like 347 for one, OUCH. |

I was like 347 for one, OUCH. yup---you read that right. 5 of them could have come out just using the extension and no ratchet. that's probably what caused #2 to go sailing into orbit. I SHOULD have checked them all after that, but I guess i'm getting a little lazy in my old age.......... |

I recently did one on our 1997 E150 with the 5.4. Luckily it was the number 2. But for me all 8 wouldn't be horrible since the van has a custom body lift. It gives me decent clearence between the engine and dash/firewall. I won't have to do plugs for quite a while yet, but I'm wondering if it would be worth replacing all the coils when I do? The van is used to transport our disabled son, so unexpected down time is even less convenient than usual.
Incidently, we bought the van from a disabled guy. He took magnificent care of it. All Amsoil fluids since first changes, OEM replacement parts including the brand new transmission at 140k, reciepts for literally everything. 197k on it now and runs nearly like new. I'm impressed with this Ford. |

my truck has 90000 on it now. the expeditions F150's tend to dam up at the back of the hood causing water to pour all over the engine, flooding the coil/plug wells. the fleet of E350's at work don't seem to have the damming problem. they do go through coils though. my van has 160000 on it and I have changed 3 coils on it so far.
I changed ALL the coils just to be sure the truck would be reliable. i'm not sure if ford has an interval for changing them. |

There isnt a set interval. I tend to get 300 to 500 thousand miles out of my engines. So now i just go with 8 being you can get a set of 8 off the internet for about the price of 2 locally. I went with putting the 8 in and tossing the bad ones and saving any good ones for down the line. Especially for cylinders that only take a few minutes to change. About half the time its not actually the coil going bad as much as the boot developing cracks and causing them to short when wet. Not that it matters tho as i dont think you can buy just the boot. Given the price tho and if i was dealing with a van. My thinking would completely change and i would only replace as needed or maybe in your case since your getting up there in mileage. But a coil going bad in these isnt going to leave you stranded on the road. Im dealing with f150, 250, 350s. pretty safe to note half my issues are from the damming water on the back and involve the number 8 cylinder because of it. The windsor built tritons are about as bulletproof as your going to get. Not all are windsor built tho. |

» www.summitracing.com/par ··· odD2gAdQyou can just buy the boots. the ones in the link are silicone and come with dielectric grease and the springs too. it says set of boots in the title, but says sold individually in the description. if the price is per SET, it looks like a pretty good price. if price is PER BOOT, buying the accels is a much better deal at $23.25 per coil when you buy the set of 8. just google "ford cop boots" and you'll get a crapload of hits. |
